The forest soil supports a complex of animal communities of which soil arthropods are of prime importance since they constitute the major component of soil mesofauna and are useful bioindicators of ecosystem health. Considering the important role of soil arthropods in the decomposition process and maintenance of soil fertility in the soil ecosystem, the present study investigate the ecology of soil arthropods in the sal and teak forest ecosystem of Gorakhpur, U.P., India. The book provides more information on distributional pattern of soil arthropods chiefly Acarina and Collembola followed by...

It is the second book in the series of basic chemistry. First book deals with some elementary concepts like from what the matter around us made up of? Why some substances react and some not? In this book we will try to explore, actually what happens when these substances react? What are the factors which govern these reactions? We shall also perceive the properties of these substances. For our convenience we will categories the substances as acid, base, salt, metal, non-metal and carbon compounds. In the last chapter our emphasis will be at the classification of elements.

This book can be treated as a general course for secondary level students. It includes all fundamental chapters of chemistry. For convenience of study it is divided into two parts. Part 1 includes chapter pertaining to some elementary concepts of ch3emistry, structure of atom, atom and molecules and matter around us. Part 2 includes chemical reactions and equations, acid, bases and salt, metals and non metals, carbon compounds and the last lesson deals with periodic classification of elements.
